Hunter Biden agreed on Thursday to dismiss a lawsuit he brought against former New York City Mayor Rudy Giuliani and his onetime attorney Robert Costello over allegations they unlawfully hacked the first son's computer data.

Biden's attorney Abbe Lowell signed off on the suit's dismissal, as did Giuliani and Costello, according to a court filing.

No explanation for the move was provided in the court papers, but a source told NBC News "it made no sense" to continue the suit while Giuliani was in a state of bankruptcy. The source also said the case would be brought again when Giuliani was out of it.

The former mayor declared bankruptcy last year after a court ordered him to pay two election workers $148 million. The penalty came as a result of a federal judge finding Giuliani defamed the two women when he accused them of committing election fraud in Georgia.

Biden's lawsuit against Giuliani came in response to the former mayor, who worked as former President Donald Trump's attorney, obtaining an external hard drive containing data from Biden's laptop and providing it to the New York Post in the lead-up to the 2020 election. The outlet proceeded to publish a string of stories targeting President Joe Biden, then Trump's leading opponent, based on the data from the hard drive.

The first son filed the suit in September 2023, accusing Giuliani and Costello of "hacking" and "manipulating" his data, as well as sharing copies of the data with the New York Post and others.

Hunter Biden's attorneys wrote in the initial complaint:
"For the past many months and even years, Defendants have dedicated an extraordinary amount of time and energy toward looking for, hacking into, tampering with, manipulating, copying, disseminating, and generally obsessing over data that they were given that was taken or stolen from Plaintiff's devices or storage platforms, including what Defendants claim to have obtained from Plaintiff's alleged 'laptop' computer."
The younger Biden is also in the midst of a similar legal battle with Garrett Ziegler and his company Marco Polo, a top disseminator of the data.

In the suit, Hunter Biden's attorneys called Ziegler "a zealot who has waged a sustained, unhinged and obsessed campaign against" the Biden family.

Ziegler's attorney has moved to dismiss the case, arguing the lawsuit is "half-baked" and that the spreading of the data was "protected activity" because it involved a matter of "significant public interest."

Lowell did not respond to a request for comment.
